The atomic number of an element is the number of protons in the nucleus of an atom of that element.

Atoms with the same number of protons, but a different number of neutrons are called isotopes.

Answer:

In physics and chemistry, the atomic number of a chemical element is the total number of protons that each atom of that element has. It is usually represented with the letter Z.

The atoms of different elements have different numbers of electrons and protons. An atom in its natural state is neutral and has an equal number of electrons and protons. A sodium atom (Na) has an atomic number of 11; It has 11 electrons and 11 protons. A magnesium atom (Mg), has an atomic number of 12, has 12 electrons, 12 protons and a uranium atom (U), which has an atomic number of 92, has 92 electrons and 92 protons.

Answer: options are not given, here are the options.

Speed up

Slow down

Remain the same

The correct answer is In the presence of Antinomycin the Citric Acid Cycle would SLOW DOWN.

Explanation:

Actinomycin is an antibiotics gotten from streptomyces which is use to inhibit which inhibit mitochondriisl eclectron transport chain.It is a poison that affect the electron transport chain, non functional and it slow down citric acid cycle because it has the ability to block the electron Transport chain thereby slowing down citric acid cycle because it inhibit or slow down succinate-cytochrome c reductase in the electron transport chain so as to block the oxidation of NADH and ATP production.

Number the steps from when the stimulus received to when the body reacts​
Natasha2012 [34]

The given question is not complete. The complete question is:

Number the steps from when a stimulus is received to when the body reacts.

The stimulus is received by sensory receptors.

Motor neurons cause muscles to contract so the body can react to the stimulus.

The brain processes the information through interneurons.

Interneurons transfer response information to motor neurons.

Sensory neurons carry stimulus information to the brain or spinal cord.

Answer:

The body of an organism like humans reacts towards each of the external stimuli of the environment like the smell of the food and even to the internal stimulus like hunger or pain. Thus, it can be considered that one is stimulated all the time and reacts towards the constituents found in the surroundings. The entire procedure of the organism reacting towards the stimuli are as follows:  

1. The sensory receptors receive the stimulus.  

2. The stimulus information is further carried to the spinal cord or the brain by the sensory neurons.  

3. The processing of the information in the brain takes place with the assistance of interneurons.  

4. After that the response information is mediated towards the motor neurons by the interneurons.  

5. The motor neurons eventually result in the contraction of muscles showing that the body is reacting towards the stimulus.
